How many people can say they've lost count of their visits to Antarctica? In this special International Women's Day episode, Professor Dame Jane Francis (Director of British Antarctic Survey) chats to Nadia about her journey into science, fossil hunting in Antarctic mud, launching the RRS Sir David Attenborough with Sir David Attenborough, and leading change.

Iceworld is presented by marine biologist Nadia Frontier, produced in partnership with Boffin Media.
